Identifying Redundancy and Exposing Provenance in Crowdsourced Data Analysis
Crowdsourcing social data analysis
2016/5/24
We present a system that lets analysts use paid crowd workers to explore data sets and helps analysts interactively
examine and build upon workers’ insights. We take advantage of the fact that, for m...
